All API client interfaces and implementations now accept an optional CancellationToken parameter for each method. This enables consumers to cancel HTTP requests, improving responsiveness and resource management. No changes were made to core logic or return types; only method signatures and HttpClient calls were updated to support cancellation.
Introduce interfaces for all API clients and update dependency injection to use these interfaces. Refactor services and components to depend on abstractions instead of concrete implementations, improving testability and maintainability.
